DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a liquid fuel burning apparatus designed to minimize the bad odor given off during normal fire extinguishment by differentiating the amounts of lowering of the wick brought about by normal fire extinguishing means and by emergency quake fire extingushing means.
TECHNICAL BACKGROUND
Generally this type of liquid fuel burning apparatus is provided with a lowering device for detecting vibrations such as earthquakes during combustion and automatically lowers the combustion wick to extinguish the fire. This type of apparatus is designed so that when the wick is manually lowered, the lowering stroke is shortened to eliminate the bad odor given off during fire extinguishment. This is shown in FIGS. 1 through 4. In these figures, the numeral 1 denotes an oil tank having a burner section 2 on its top.
The numeral 3 denotes a wick vertically slidably installed in the burner section 2 and constantly urged in the lowering direction by a spring (not shown).
The numeral 4 denotes a wick shaft rotatably mounted on the apparatus, having attached thereto at one end a pinion 5' meshing with a rack 5 fixed to the wick 3 and at the other end a knob 6 for the wick shaft 4, the arrangement being such that the rotation of the knob vertically moves the wick 3.
The numeral 7 denotes a support fixed to the wick shaft 4 by a screw 8, and 9 denotes a rotary plate fixed to the support 7 and having a pin 10 fixed to the upper portion thereof.
The numeral 11 denotes a ratchet wheel rotatably mounted on the support 7 and formed around its outer periphery with a projection 11a and a plurality of teeth 11b, said ratchet wheel 11 having a throughgoing slot 11c in which said pin 10 slides.
The numeral 12 denotes friction members fixed to the opposite surfaces of the ratchet wheel 11 and urged by friction members 13 in the form of spring sheets.
The spring members 13 are held in position on the support 7 by restraint members 14.
The numeral 15 denotes a vibration sensing device attached to the top of the oil tank 1 and comprising a weight 16 and a lever 17 operable by said weight 16, said lever 17 being formed at its front end with a locking device 18 for the wick 3.
The locking device 18 comprises the lever 17, an auxiliary lever 19 mounted on the front end of said lever 17, and a spring 20 for urging said auxiliary lever 19 to the ratchet wheel 11.
The front end of said auxiliary lever 19 is formed with a locking portion 19a adapted to mesh with the teeth 11b formed on the ratchet wheel 11, the engagement between said locking portion 19a and the teeth 11b preventing reverse rotation (counterclockwise rotation, in the figure) of the ratchet wheel 11.
Further, the front end of said lever 17 is formed with a stop 17a adapted to abut against the projection 11a on the ratchet wheel 11 to stop rotation of the ratchet wheel 11. In addition, the optimum burning position for kerosene fuel sucked up by the wick 3 is so designed that it corresponds to the height (point a in FIG. 4) of the wick 3 obtained when, as shown in FIG. 2, the stop 17a on the lever 17 abuts against the projection 11a on the ratchet wheel 11 and the pin 10 fixed to the rotary plate 9 abuts against the terminal end of the throughgoing slot 11c formed in the ratchet wheel 11.
Further, the lever 17 and auxiliary lever 19 of said locking device 18 are adapted to move in the direction of arrow A in FIG. 2 when the vibration sensing device 15 is actuated, thereby canceling the locking between the ratchet wheel 11 and the locking device 18.
The numeral 21 denotes an emergency fire extinguishing device so designed that a knob 21a is rotated separately from the vibration sensing device 15 to move the lever 17 which is connected to the knob 21a with a chain, etc., in the direction of arrow A in FIG. 2, thereby canceling the locking between the locking device 18 and the ratchet wheel 11.
In addition, 22 denotes an inner wick cylinder and 23 an outer wick cylinder.
In such apparatus, when it is desired to decrease the height of the wick 3, the k
